To alt whom it may concern.

Be it, known that I, CHARLES VHITNEY STEVENS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new anduseful Improvements in Ceiling Constructions, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

My invention relates to a ceiling construction and, more specifically, to a ceiling construction which is supported on cushions.

One of the objects of my invention is to provide an improved ceiling construction which will prevent soundfrom being transmitted from the floor above, and which will permit the ceiling to adjust itself in case of shrinkage and settlement, thereby preventing cracking of the ceiling. Further objects will appear from the detailed description to follow and from the appended claims.

In the drawings, in which several embodiments of my invention are shown- Fig. 1 is a perspective view showing a joist, part of the floor supported thereby, and the cushion supports for supporting the ceiling construction from the joists;

Fig. 2 is a vertical section showing the cushioning support and part of the joist;

Fig. 3 is a bottom view of a suspension member forming part of the ceiling support;

Fig. 4.- shows an embodiment of my 1nvention used in fireproof building construction, the v1ew being a vertical section;

Fig. 5 is a perspective view of the pad plurality of stringers 14, to which the laths 15, which support the plaster'16, are' secured.

The-pad-supports 13 may beformed of I sheet-metal having a vertical U-shaped pora horizontal. rectangular portion 18 struck up from the U-shaped portion 17 for engaging the lower edge of the joist 10 for posiholder is provided with a suspension-device 22, which comprises a U-shaped portion 23 for embracing the stringer 14, a shank-portion 24 extending up through an opening in the pad-rest, and a bearing-plate or washer 25 to which the upper end of the shank 24 is secured. The shank portion extends loosely through the opening in the pad-rest "so as to be free to move with respect thereto.

For holding the pad 20 and the suspension member 22 in proper position with respect For suspending the" ceiling construction from the pads, each pad} to the pad-supports 13, the suspension-member may be provided with a shoulder portion 26 for engagement with a fiber washer 27 located beneath the pad-suppo-rts. Thisfiber washer serves to hold thesuspensionmember in position with respect to the padsupports, but due to the material of whichthe washer is composed, it does not readily transmit vibration. j v

The stringer 14 may be secured to the U- -shaped portion 23 of the suspension-member by means of a nail 28 extending through the wide. part 29 of the U-shaped portion. I

In this construction there is no connection between the joist 1 0 and the ceiling construction, except through the cushioning pads 20. Because of this cushioned connection, .sound will not be readily transmitted from the floor above to the ceiling-construction. tion, a shrinkage or settlement of the joists 10 and associated parts is not apt to cause the plaster of the, ceiling construction to crack, as there is no rigid, unyielding connection between the joists and the ceiling construction. I

In the form of my invention shown in Figs. 4 and -5, I' have shown my invention in connection with a fireproof construction. In this construction the floor construction comprises a horizontally-extending body portion of cement, or the like, indicated at 30, and the ceiling construction may comprise an expanded metal web 31 imbedded in the plaster 32, for supporting the plaster. T he Also, because of the yielding conneehorizontally-extending plate 39 imbedded in the cement 30. .The expanded metal web 31 may be suspended from the cushioning supports by means of a suspension-member 40 having a. head 41 at its lower end, on which the webr'il rests, and having a bearing-plate 42 at its upper end, which rests on the pad 34.

In this form as in the form of Figs. 1, '2 and 3, there is no connection between the floor construction and the ceiling construction except through the cushioning supports. In the form of my invention shown in Fig. 6, it is shown in connection with a fireproof construction comprising a horizontally-extending floor construction 43, of cement or the like, in which are imbedded reinforcing Steel members, such as the I-beams 44. The ceiling construction 32 may be the same as in the form of Fig. 4, as also the pad-support and suspension-member. In this form, however, the aperture 36 of the car 35 receives a hook 45, the shank of which extends over and is secured to the I-beam 44. In this construction, also, there is no connection between thefloor construction and the ceiling construction except through the cushioning pads.

One ofthe functions of the fiber washer" 27 is to hold the suspension device 22 against upward movement when the laths 15 are .being nailed to the furring strips or stringers 14. After the plaster 16 has been applied,

the ceiling .construction may settle so that the washer 2? will be entirely out of contact with the horlzontal pad rest portion 19.

I clalm as new and desire to. secure by Letters Patent:

1-. A building construction comprising a horizontally-extending support, a ceiling construction therebeneath, and a plurality of cushioning supports for suspending said ceilpads, eachpad servingas a sound insulator- .ing'construction fromsaid horizontal support, each cushioning support serving as a sound indicator to prevent the ready trans,- mission of sound. from the horizontally extending support to the ceiling, and also as a Kielding ceiling support whereby the possiility of cracking of the ceiling plaster is minimized.

2. A building construction comprising a horizontally-extending support, a plurality of pad supports secured thereto, a plurality of pads bearing on 'sald supports, respective:

ly, and a ceiling construction underneath said horizontal support and supported by said to prevent ready-transmissionof sound from the horizontally extending support to the rality of pads, one supported on each plate,

and a ceiling construction underneath said horizontal support and supported by said pads, each pad serving as a sound insulator to prevent ready transmission of sound from the horizontally extending support to the ceiling and also as a yielding ceiling support whereby the possibility of cracking of the ceiling plaster is minimized.

4. A buildingv construction comprising a horizontally-extending support, a plurality of pad supports secured thereto, each comprising a horizontal supporting plate, a plurality of pads, one supported on each plate, a ceiling construction underneath said pad supports, and means bearing on said pads for suspending said ceiling construction, each pad serving as a sound insulator to prevent the ready transmission of sound from the horizontally extending support to the ceiling,

and also as a yielding ceiling support whereby the possibility of the cracking of the ceiling plaster is mlnimized.

5. A building construction comprising a horizontally-extending support, a plurality of pad supports secured thereto, each comprising a horizontal apertured supporting plate, a plurality of pads, one supported on each plate, a ceiling construction underneath said pad supports, and means for suspending said ceilingconstruction comprising a plurality of suspension members, one carried bv each pad, each comprising a hook member, each supporting plate being apertured to receive a hook member, each pad serving as a sound insulator to prevent the ready transmission of sound from the horizontally extending'support to the ceiling, and also as a yielding ceiling support whereby the possibility of cracking of the ceiling plaster is minimized.

6. A building construction-comprising a horizontally-extending support, a hook member secured thereto, a pad-support having an I apertured portion to receive said hook, a

pad for sald support, and a ceiling constr-uction beneath said horizontal support sup ported by said'pad, said pad serving as a sound insulator to prevent the ready trans- .mission of sound from the horizontally ex- CHARLES WHITNEY STEVENS.
